Home page URL: Security reports for W3 Total Cache
Application: W3 Total Cache
Published on: Oct 10, 2026
Research Description: The W3 Total Cache WordPress plugin before 2.10.6 does not confine a media-import file copy to the document root, nor enforce an effective file-type restriction on it, allowing users with the Author role or higher to plant content that, once an administrator runs the import, copies an arbitrary server-readable file into a publicly served directory, exposing it to unauthenticated retrieval.
Affected versions: max 2.10.6.
Status: vulnerable
